sdeshpan has asked for the wisdom of the Perl Monks concerning the following question:

All,

I have been trying to run a CGI script on the tomcat app server by enabling CGI support through the configuration files in tomcat (on windows xp). I have been able to set up this configuration successfully and a sample "hello world" program works ok.

However, now I am trying to run my actual code, which connects to a DB using DBI, but it fails and gives me the following error:

Error ORA-12545: Connect failed because target host or object does not
+ exist (DBD ERROR: OCIServerAttach) connecting to DBI:Oracle:host=<ho
+stname>;sid=<sid>;port=1521

As per WW's suggestion, here is the "connect" code that I am using: 

# DBI Initializations
my $driver = 'Oracle';
my $hostname = 'host=oradev;sid=oradev;port=1521';
my $user = 'user';
my $password = 'password';
my $dsn = "DBI:$driver:$hostname";

my $dbh = DBI->connect($dsn,$user,$password) or croak "Error $DBI::err
+str connecting to $dsn\n";

I checked the TNSNAMES file and I am able to successfully ping and tnsping to the <hostname>. I wonder what might still be missing! Can anyone point me in the right direction?

Cheers,
Sarang D.

    I suspect we'll need to see your connect code to be much help. Suggest you post it as an update within your OP.

      WW - I have posted the "connect" code in my post (original as well as a later one) already. Is that not what you were asking for?

    Can you connect using sqlplus?

      Yes, I can connect using sqlplus as well as toad. I can also ping the DB machine and tnsping is successful. This makes me believe that everything on the oracle client is ok. I am also providing the "connect" code here that I am using: 
      # DBI Initializations
my $driver = 'Oracle';
my $hostname = 'host=oradev;sid=oradev;port=1521';
my $user = 'user';
my $password = 'password';
my $dsn = "DBI:$driver:$hostname";

my $dbh = DBI->connect($dsn,$user,$password) or croak "Error $DBI::err
+str connecting to $dsn\n";

      the last line is where it fails and gives me the error message!

        Does 
        my $dsn = "DBI:$driver:oradev";
my $dbh = DBI->connect($dsn,$user,$password);

        make any difference?

        The code you currently have bypasses the tns alias, the code above uses the alias.
